It seems to be a known issue in Karaf 4.0.8… You can’t do something about it (other than wait for the OH2 maintainers team to upgrade the Karaf version being used)
Thanks Dim, that’s a relief. Btw, about opcode 42, i am using OSX ssh to directly connect to openHAB2, if anyone else using OSX to connect to their servers they might be having the same problem.I just chose to ignore at the moment…
